ICE-CAP.

Specification of Letters Patent. Patented Aug. 29, 1911.

Application led June 21, 1910. Serial No.. 568,215.

To allvwi-om it may concern:

Be it known that I, RUBY A. BARNES, of the city of Baltimore and Stateof Maryland, have invented certain vImprovements in Ice-Caps, of whichthe following is a specification.

This invent-ion relates to an ice cap for invalids, formed of somepliable material such for instance as rubber cloth, which embraces acovering adapted to conform to the shape of the head ofthe patient, anda dome-shaped ice receptacle which dueto its fullness, extends outwardlyand laterally to a considerable distance beyond the head covering; andit.consists in a peculiar construction of the device whereby the abovedescribed shape of the ice cap is maintained, as will hereinafter fullyappear.

In the further description of the said invention which follows,reference is made to' the accompanying drawing forming a part hereof,and in which,-

Figure 1 is an exterior side View of the completed ice cap, and Fig. 2is a section of Fig. 1 taken on the dotted line 9.-2. and 7 are views ona much reduced scale, of the blanks which when the complete device shownin Fig. 1.- K Y In the construction of the improved ice cap, I cut froma sheet of rubber cloth, the blank 1 which consists of a four pointedstar, the points a of which are rounded as shown and in the center ofthe blank, form a circular orifice b with radial slits c extending alimited distance therefrom to allow of its enlargement in the insertionthrough the blank of `the capped filling nozzle 2 which is shown only inFig. 1.

3 is a centrally perforated reinforcing disk which is cemented to theouter surface of the star shaped blank 1 to strengthen it when the jointbetween the nozzle 2 and the blank 1 is formed.

4 is a rectangular blank the upper portion or edgeof which 's notched soas to produce the four triangular points d.

In uniting the blanks 1 and 4, the four rounded points a of the formerare placed in the spaces between the triangular points (Z of the latter,and the adjoining edges of the two parts cemented together. Theends'joint of the blank 4 are then united by a cemented By thisconstruction, the fullness in the dome-shaped ice receptacle A, bestshown in Fig. 1, is produced. I then turn in the lower portion or edgeof the device as so far constructed, on the dotted line min Fig. 4, andto the edge e of the introverted portion, cement the edge of thecircular blank `5 which forms the crown of head covering. The device isnow in its proper shape, butdue to the pliability of the material used,and of its uniformity in thickness, the head coveringproduced by theintroversion of the lower portion of the blank 4, and its crown asdescribed, will not retain any predesigned depth, and is liable to bechanged in handling the device, and in its application to the head ofthe patient, -I therefore cement to the outer surface of the inner andouter parts of the blank 4 which are adapted to encircle the head, therectangular reinforcing folded strip 7 the ends of which are attachedtogether with cement.

It will be understood that the ice cap constructed as described whilebeing flexible throughout, vwill maintain its yshape as regards thedepth of the head covering and the' relation which that part of `thedevice bears'to the dome-shaped ice receptacle in handling, in itsapplication to the headV of the patient, owing to the difference inthickness of the said parts; and any distortion oi' disarrangement ofthe dome-shaped ice receptacle is not communicated to the covering incontact with the patients head,should the patient be placed in areclining position with his head on a pillow.

' I claim as my invention,

1. In an ice cap, a iexible dome-shaped ioe receptacle with its edgeintroverted to roduce a continuous outer and an inner wall, the innerwall forming the lower part of a head covering, combined with a flexiblecrown which is secured to the edge of the inner wall, and an introvertedflexible reinforcing strip which is cement-ed to the introvertedVportion of the device which is adapted to encircle the head,substantially as specified.

2. An ice cap embodying an ice receptacle which consists of arectangular flexible blank with its upper edge notched to produce a'series of points, and its ends united receptacle is produced,substantially as to vform a ezible annulus, combined with a specled.
